Operations Problems

  • Another spate of inconsistencies in the database brought down ATLAS for 11 hours on Tuesday. Similar to an incident in July when 1 subrequest without an entry in id2type brought the instance down - this time there were many orphaned subrequests. All subrequests had to be invalidated. This incident will be reviewed on Wednesday.

Blocking Issues

  • We need to understand the cause of the new database disk array hardware problem before we can migrate production databases over to it.
